LaunchProcess.vi breaks during build

[hfettig]

For some reason I am currently getting this message when I try do build my project:

Error 1 occurred at A VI broke during the build process from being saved without a block diagram. Either open the build specification to include the block diagram of that VI or enable debugging to include the block diagrams of all VIs in the build. Report this error to National Instruments technical support.

C:\Program Files (x86)\National Instruments\LabVIEW 2017\vi.lib\JKI\JKI SMO\SMO\Private\LaunchProcess.vi

Click the link below to visit the Application Builder support page. Use the following information as a reference:

Error 1502 occurred at AB_Source_VI.lvclass:Close_Reference.vi -> AB_Build.lvclass:Save.vi

Possible reason(s):

LabVIEW:  Cannot save a bad VI without its block diagram.

Possible reason(s):

LabVIEW:  An input parameter is invalid. For example if the input is a path, the path might contain a character not allowed by the OS such as ? or @.

 

The VI is perfectly fine outside the build process. Any ideas what could be the issue here?

Not a good sign that there were no replies here, but it's worth a shot.

After successfully building my application for months, I am also now getting this same error on the same VI. Were you ever able to find a resolution to the problem?
